Abstract
A thread form is shown which is used to make a threaded pipe connection capable of being screwed together and subsequently unscrewed. A pin member is provided having external threads with stab flanks and load flanks and flat crests and roots for mating with the mating internal threads of a box member to make up a pipe connection. One of the stab or load flanks is made up of two facets and three radii. The other selected flank is made up of three facets and four radii, giving it irregular features forming a complex geometric profiles. The thread form can be used to form a premium threaded connection which is used with such tubulars as casing and tubing for oil, gas, water and waste disposal wells.
